i I SASH-VENTILATOR.

Specification of Letters Patent.

Patented Sept. 18, 1906.

Application filed April 24, 1906. Serial N01 313,468.

To all whom it may concern:

Be it known that I, HENRY SoHELLER, a citizen of the United States of America, residing at Brooklyn, in the county of Kings and State ofNew York, have invented new and useful 1m rovements in Sash-Ventilators, of which t e following is a specification.

This invention relates to improvements in sash-ventilators, the object of the invention being to provide a simple and effective construction of ventilator which may be readily applied to sashes of ordinary construction and opened to any desired degree to secure free ventilation of a room without creating a draft.

In the accompanying drawings, Figure 1 is an inside elevation showing the application of the invention to one of the sashes of a window. Fig. 2 is a cross-section on line 2 2 of Fig. 1. Fig. 3 is a plan view of the ventilator.

Referring to the-drawings, 1 designates a window-sash having aventilation-opening 2, which may be formed by removing one of the panes of the sash or in any other preferred manner. A closure is provided for controllingthe opening 2, said closure comprising companion inner and outer shutters 3 and 4. Each of these shutters is formed of a frame having an opening for the reception of a transparent pane 5, retained in position by suitable flanged keepers 6. These panes allow of the entrance of light through the closure when either of the shutters is in closing position.

The shutters 3 and 4 have their frame por tions united at their lower ends by a union 7, which is provided with bearing-sleeves 8, revolubly mounted on a pivot-rod 9, arranged at the base of the opening 2. From the union 7 the shutters 3 and 4 extend upwardly in divergent relation and are connected and braced adjacent their upper ends by cross pieces or braces 10, joining the side portions thereof. Each shutter is also provided at its upper end with a handle or finger-piece 11 for convenience in adjusting the closure, said handles being adapted to'enter receiving-recesses 12 in the upper wall of the opening'2 to allow the shutters totightly close the open- It will be observed that the shutters are so arranged that upon swinging the closure as a whole inwardly or outwardly the shutter 3'or the shutter 4 may be brought into position to close the opening 2 and adjusted to regulate the size of the same, so as to permit of the entrance of more or less air into a room. I A

locking-bar 13 is pivoted at its outer end to the outer shutter 4, as shown at 14, and provided at its inner end with a suitable handle or finger-piece 15, extending through and movable within a slot in the frame of the inner shutter 3'. The lower edge of the bar 13, which is curved to conform withthe arc of movement of the closure, is formed with spaced recesses or teeth 16, adapted to engage a locking-pin 17 on one of the side walls of the opening 2, whereby the shutter may be conveniently locked in any desired position of adjustment.

Fig. 2 shows in full and dotted'lines the closure adjusted to an intermediate-open position and to a position in which the inner shutter 3 .closes the opening 2 and it will be apparent that upon swinging the closure 'inward the shutter 4 may bebrought into posi- When the closure tion to close the opening. is in open position, the air from the exterior flows downward through the space between the sash and outer shutter 4 and thence intothe room through the spaces between the shutter and sides and top of the inner shut-" ter 3, thus preventing the passage of a direct draft of air across the rgom. in other words, the shutter 3 will act as a deflector to break up or diffuse the entering current ofv air and prevent it from sweeping across the room in an unbroken current.

The ventilator maybe employed for general purposes to control a ventilation-open ing in any type of str cture and may be applied to a window-sasli of ordinary construction by sim ly removing one of the panes from the sas .and substituting the ventilating device in its place.

Having thus described the invention, what is claimed as new is- I 1. The combination with a sash or other structure having a ventilation-opening, of a closure therefor comprising shutters pivoted to swing inunison and projecting beyond oposite sides of the opening, and means for iiolding the closure in a desired adjusted position. 2. The combination with a sash or other structure having a ventilation-opening, of a closure therefor comprising diver ently-arranged shutters pivotally mounte at their convergent ends and connected to swing in unison, said shutters being arranged upon opposite sides of the opening, and means for olding the closure in a desired adjusted position.

and a rack carried by the closure and adapted to be engaged With said locking member to hold the closure in a desired adjusted position.

4. The combination with a sash or other structure having a ventilation-opening and a pivot-rod at the base of the opening, of a ciosure therefor comprising shutters arranged in divergent relation and connected for movement in unison, said shutters being arranged on opposite sides of the opening pivoted at their convergent ends to said rod, means for connecting the ripper of the ciosnre at any pointhetween the shutters to the sash or structure.

5. The combination with a sash or other earns o structure having a ventilation-opening and a locking projection, of a closure pivotally mounted in said openingand comprising oppositeiy-arranged companion shutters connected to swing in unison, and a curved rackhar pivoted toone of the shutters and having a handle extending through the other shutter, whereby the closure may be engaged with the locking projection to hoid the closure in any desired adjusted position.

6. A ventilating device comprising a pair of divergentiy arranged shutters connected to move iniunison and pivotaiiymounted at their convergent ends, and a fastening memher extending between the divergent ends of the shutters for engaging a compiernentary fastening rnernher to secure the device in a desired uste-d position.

In testimony whereof i a'HiX my signature in presence of two Witnesses.
